My Winter Vacation Homework Was Checked and I Was Asked Where to Catch the Dinosaurs?

Traveling through a parallel world, Shen An became a biology college student and spent a winter vacation completing his winter vacation homework! Just as Shen An was about to take out his winter vacation homework, a group of heavily armed special police officers broke into the classroom. "Shen An, come with us!" At the Criminal Police Headquarters, a group of top biologists from the Dragon Kingdom looked at Shen An's winter vacation homework and fell into confusion. Interrogate Minori! The policeman looked at the information in his hand with a solemn expression. "Everyone else is enjoying their vacation, what are you doing during the winter vacation?" Shen An said honestly: "Do your winter vacation homework!" "Why do you have to go abroad to do your winter vacation homework?" "Go overseas to collect the materials needed for the ecological tank. The materials are different in each continent." "Then why did you join the mercenaries?" "I need money to buy materials!" "If you just need money, why are you ranked third on the killer list!" "It should be the part-time job that brings me the most money. I've done many part-time jobs!" "I heard that MIT wanted to appoint you as a foreign professor. Why did you refuse?" "They want to help me complete the biotank experiment, but I don't agree!" "Delta Force, a nuclear submarine was robbed. Was it you?" "They owed me wages, so I drove away to pay off the debt!" Police: "Last question, where did you catch the saber-toothed tiger?" Shen An: "Dinosaurs evolved in the ecological tank!" Shen An answered the question honestly, but found that the people sitting next to him were confused.
